Hi @GloriousDove367, the blueprint BP_PickupCube in this video seems to be an old version of pickingup function in VR. In UE4.27, the VR pack should like this:
I’m not familiar with VR but I think now just adding a GrabComponent can make the cube to be picked up.
As for the logic, when you grab the cube, it should disable physics and attach to your controller (your hand). And when you release, the cube should detach from the controller. In this video, when you put the cube in the target position (use overlap event to check this), the cube call Detach event to detach from controller and then set the cube’s position and then do other things.
